Application filed December 10, 1914. Serial No. 876,518.

T0 all whom t may concern Be it known that WHITNEY 7. SAUN- D'nns, subject of King of Great Britain, and citizen of Dominion of Canada, residing at Red Deer, in the Province of Alberta and Dominion of Canada, have invented certain new and useful Improvements in Self-Extinguishing Lamp-Burners; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to lamp burners and the primary object of the invention is to provide a lamp burner which is constructed so that when the wick is turned down the light will be automatically extinguished.

Another object of this invention is to construct a lamp burner which has an auxiliary wick carrying sleeve mounted within an outer sleeve and to provide a plurality of corrugations upon one side of the wick carrying sleeve for action upon by the pinion for turning the wick up or down.

Another object of this invention is to connect to the outer tube an extinguishing mechanism which is formed of a length of wire bent to properly engage the upper surface of the wick when the same is turned down and to provide a lug formed upon one side of the inner wick carrying tube for engaging the extinguishing device for automatically extinguishing the lighted wick when the same is turned down.

With the foregoing and other objects in view this invention consists in such novel features of construction, combination and arrangement of parts as will be hereinafter more fully described, illustrated in the accompanying drawings and claimed.

ln describing the invention in detail reference will be had to the accompanying drawings wherein like characters of reference designate like or corresponding parts throughout the several views, and in which Figure 1 is a sectional view through a lamp burner constructed in accordance with this invention. Fig. 2 is a detail'perspective view of the tube. Fig. 3 is a side elevation of the wick carrying tube, and Fig. a is a fragmentary perspective view of a part of the construction of the tubes of the burner.

Referring more particularly to the drawings, 1 designates a fragment of a lamp which has the burner construction 2 detachably connected thereto in the ordinary manner. The burner construction 2 embodies a body portion 3 and a hinged wick protector 4, and the supporting base 5 which `is connected to the lamp body 1. The supporting base o of the lamp burner 2 has a substantially rectangular shaped sleeve 6 secured to the central portion thereof and extending upwardly therefrom. lThe sleeve 6 has a second sleeve 7 slidably mounted therein, which second sleeve has its edges cut away for substantially two-thirds of the length of the same as is clearly shown in Fig. 3 of the drawing. The sleeve 7 carries a wick 8 such as is ordinarily used in kerosene oil lamps. The tube 7 has its side 8 corrugated, which corrugations are adapted for engagement by the pinion 9 which is carried upon the rod 10. The rod 10 projects out of the supporting base 5 of the lamp burner and has a thumb nut (not shown) mounted thereupon as is ordinary in the construction of lamp burners. The pinion 9 extends through an opening 12 which is formed inthe sides of the sleeve 6. The sides of the tube 7 which are free from connection with each other at the upper end of the tube, as is clearly shown in Fig. 3 of the drawings, will permit of the spreading thereof, for access to be gained to the w1ck 8 for trimming the same, or for inserting a new wick into the tube.

The tube 6 has projections 14C and .15 formed upon the upper edge of the s lde opposite to the side in which the opening 12 is formed. The projections 14C and 15 are bent outwardly and downwardly and have their terminal ends rolled upon themselves for forming bearings for the straight portions 16 and 17 of the wire 18 which forms the extinguishing mechanism. The projections 14 and 15 have their'inner edges spaced from each other and provided with shoulders 19. Thelength of wire 18 is bent to form substantially a U-shape, the vertex 20 of which is provided for engagement with the upper edge of the wick 8 for the purpose of extinguishing the flame of the wlck when the same is lighted. The arms 21 and 22 of the Ushaped portion are bent at 23, intermediate their ends and extend inwardly toward the sleeve 6 for shaping the arms 21 and 22 in substantially a bell crank lever shape for properly positioning the vertex or straight portion 20 thereof for engagement with the wick end and to permit of the section 24 of the wire to be seated rotatably in the rolled terminal ends of the projections 14 and 15. The terminal end of the wire 18 projects out of the rolled end of the projection la and is bent downwardly therefrom having a weight 25 mounted upon its terminal end, the purpose of which will be hereinafter more fully described. The sections of the Wire 16 which is disposed intermediate the facing edges of the projections 14 and 15 is also bent to form a substantially U-shaped loop 26, which projects toward the sleeve 6 and is adapted for engagement by the lug 27. The lug 27 is formed upon the side 28 of the sleeve 7 and extends outwardly at substantially right angles thereto for engaging the U-shaped loop 26 for rocking the wire 18 for causing the section 20 thereof to engage the upper end of the wick 8 when the wick is turned down into the tube G, for extinguishing the flame. The weight 25 is of sufficient size to automatically move the section 20 away from the upper end of the wick S when the loop 26 is relieved from pressure by the lug 27. The downward movement of the loop 26 is limited by the shoulders 19 formed upon the edges of the projections 14 and 15.

From the foregoing description taken in connection with the accompanying drawings the advantages of construction and of the method of operation of the improved self extinguishing lamp burner will be readily apparent to those skilled in the art to which this invention appertains and, while in the foregoing description, the principle of the operation of this invention has been described together with various features of construction, it is to be understood that certain minor features of construction, combination and arrangement of parts may be altered to suit practical conditions provided such alterations are comprehended within the scope of what is claimed.

What is claimed is z- 1. ln a lamp burner, a substantially rectangular sleeve, a wick carrying sleeve mounted within said rectangular sleeve and having the upper ends of its sides free from connection to each other, one of said sides of said wick carrying sleeve being corrugated, a pinion for engaging said corrugation for moving said wick carrying sleeve vertically within said rectangular sleeve, and means carried by the upper end of said rectangular sleeve for engaging the upper end of a wick and extinguishing the same upon downward vertical movement of said wick carrying sleeve within said rectangular sleeve.

2. In a lamp burner structure, a substantially rectangular sleeve, a wick carrying sleeve slidably mounted within said sleeve, said sleeve having projections formed upon the upper end of one side thereof, said projections bent downwardly and outwardly and having said terminal ends rolled upon themselves, a wire bent to assume substantially a rectangular shape having one side rockably mounted within said rolled ends, the other side of said wire rectangle being positioned for engagement with the upper end of a wick upon downward sliding movement of said wick carrying sleeve within said rectangular sleeve, and means for automatically moving said wick engaging side of said wire rectangle out of wick engaging position upon upward sliding movement of said wick carrying sleeve within said first named sleeve.

3. ln a lamp burner structure, a substantially rectangular shaped sleeve, a wick carrying sleeve slidably mounted within said sleeve, said wick carrying sleeve having one side corrugated, a pinion for engaging said corrugations for moving said wick carrying sleeve vertically within said rectangular sleeve, said first named sleeve having projections formed upon the upper end of one side thereof, said projections being bent outwardly and downwardly and having their terminal ends rolled, a wire bent to assume substantially a rectangle having one side rotatably mounted within said rolled end, the other side of said wire rectangle being positioned for engagement with the upper end of a wick upon downward movement of said wick carrying sleeve within said first named sleeve, a loop formed upon the side of said wire rectangle which is mounted within said rolled end, a lug carried by said wick carrying sleeve for engaging said loop for moving said wick engaging end over the upper end of said wick carrying sleeve, and a weight connected to said wire rectangle for moving said wick engaging end away from the upper end of said wick carr Ying sleeve upon upward movement of said wick carrying sleeve.

In testimony whereof l afhx my signature in presence of two witnesses.
